Resource abundance, population fitness and population diversity. A – C and J – L. The 20 most abundant resources are plotted through time. The darker a curve, the higher the abundance of this resource throughout the run. The top and bottom row contain, respectively, runs from the local and null model (for each selection regime a run). If visible at this scale, the initial phase is indicated by a gray background. D – F. Maximum and median fitness of the population through time. Dark shaded areas indicate the local model, light shaded areas the null model. G – I. Diversity in the population measured as the number of different network dynamics through time. Each 1000 time steps 1000 individuals were sampled and grouped by their network dynamics. The number of different groups is plotted. Grouping by phenotype gave qualitatively similar results.
